Yesterday I had a chat with one of our DBA's (an ORA600 kind of guy) who was reluctant to go for an OCM. He said it was, because of the mandatory classes, a lot of money for what it represents. The OCM is all about true DBA actions: Creating a failover system, letting a standby database take over, ... so at least it's about real life situations and not about memorizing answers.

Thanks for your reply, I am oracle certified professoinal for 9i and 10g and now planning for OCM, as you mentioned it requires two mandatee classes and luckily I have completed that mandatee classes from my company.

It's two day's hands on test, It's about managing the databases rather memorazing answers. What I have got information from Oracle site is exams is for 16 Hours practical test (8 Hours each day) and they will gives you 8 real time scenario.. that are based on exam objectives.... but this exams fees is very high.. it's cost $2000.
